Given Operation London Bridge has been rehearsed and prepared for a very long time, I assume this is something news operations are prepared for.

Think BBC have at least a couple rehearsals each year.  I seem to recall preparation includes if the news breaks during Breakfast, as well as if during the daytime.  I think it's reasonable to speculate that obit packages are being hastily updated at this moment, if only to include the photo from the Queen meeting Liz Truss on Tuesday.  Similarly broadcasters ensuring news studios/programmes have the likes of black ties close-by over the next few days just in case.

They were caught out a tad by the Prince Philip's death last year although I think given he was in and out of hospital, it wasn't a shock. This news coverage reminds me more of when Pope John Paul II died, he was in very poor health and it was a matter of when rather than if.
